Fluid chart calculations in lbf

Need help!
I am trying to implement a Fluid Input-Output balance chart using a LBF I created.

I need the LBF to help me achieve the following:

  1. TOTAL INPUT to be calculated by adding the fields named ORAL, RECTAL, IV, OTHER ROUTES.

  2. TOTAL OUTPUT to be calculated by adding URINE, VOMIT, TUBE, RECTAL OUTPUT, OTHER ROUTES.

  3. BALANCE to be calculated by subtracting TOTAL OUTPUT from TOTAL INPUT.

  4. 24Hr FLUID BALANCE to be calculated by adding all BALANCE within 24Hrs.

I don’t have any coding skills/experience but I may be able to find someone who does.

OpenEMR Version 5.0.1 (4) with XAMPP
I have had some customizations effected by someone else.

OS: Windows 11.

Web Browser: Google Chrome

Any help will be greatly appreciated!
